"If people are noticing my boobs in a movie and saying they do what real boobs do, then that's great," the typically outspoken Winslet tells August's Harper's Bazaar, which also notes that Winslet's bosom has even earned raves from Oprah Winfrey.

But, as happens, all good things must come to an end. "I'll be 34 in October. I can't keep getting away with [nudity]," says Winslet. "There was so much of it in The Reader because the story required it, but people have seen enough of my bum and my boobs. I have to put them back."

Harper's also says Winslet's legs may also face a similar expiration date – despite the good care that the star says she has always taken when it comes to herself.

"When everyone was out getting plastered, I didn't do all of that. I was working. I was doing life," says Winslet. "Now that I look back, I feel very lucky. I've never taken drugs, never been offered cocaine."

Besides there are husband Sam Mendes and children Mia, 8, and Joe, 5, to consider.

"[R]omance to me is spontaneity," Winslet insists. "It's not diamond earrings; it's a bunch of daffodils that's freshly picked from the field. Or just a little thing like Sam calling me at three in the afternoon, saying, 'I'm coming home now. I'm done for the day.' It's romantic because he just thought, 'I'll go home. I want to be with Kate and the kids.' "
